A letter of protection (LOP) is a written promise that lets you get medical treatment after an injury without paying up front. Your attorney, you and your medical provider agree that the provider will wait for payment until your case settles or ends in a judgment, and will be paid from that money. It can open the door to care you could not otherwise afford. It also carries real risks for you, and most people hear about those only after they have signed.
We are a Utah law firm that handles personal injury, workers’ compensation and other injury-related matters. This guide explains what an LOP is, when it makes sense, what it can cost you, and how it differs from a lien.
TL;DR
- An LOP is a contract in which a provider agrees to defer billing, and your attorney promises to pay the provider from any settlement or judgment. It is used mainly in personal injury and wrongful death cases.
- An LOP is not a statutory lien. It is a contractual promise, which is why it raises ethics questions for the lawyer who signs it.
- You stay personally responsible for the medical bill, even if your case settles for too little or you recover nothing.
- Providers working under an LOP may charge higher rates than your health plan would allow, which can shrink what you take home.
- Your lawyer must explain these risks and get your informed consent in writing before issuing one.

What a letter of protection is
After a car crash, a fall or a dangerous workplace, the first bills arrive long before any settlement does. An LOP is the tool that bridges that gap. It is a binding contract between an injured person, their attorney and a medical provider. The provider treats you and holds off on billing. In return, the attorney promises that the provider will be paid directly out of any future settlement or court-ordered judgment.
In practice, the letter usually goes out on the attorney’s letterhead and does a few things:
- Identifies you as the patient and confirms that the attorney represents you in an injury claim.
- Asks the provider to treat you and to delay collection while the case is pending.
- States that the attorney will withhold money from the recovery to pay the provider’s bill.
- Often asks the provider to send itemized bills and records so the claim can be documented.
The key point is the direction of the promise. The letter protects the provider’s expectation of payment. As one personal injury firm puts it plainly, an LOP protects the medical provider, not the patient. That is why you should understand it before agreeing.
When an LOP is used
An LOP is primarily used in personal injury and wrongful death actions in situations like these:
- You have no health insurance.
- You have used up the coverage you do have, such as medical payments coverage on an auto policy.
- You need specialized care that your plan does not cover.
- Your health insurer has denied benefits and you cannot wait for the dispute to resolve. Insurance denials are common enough that it helps to know your next steps before treatment gaps open up.
If you have good health insurance, an LOP is often not the best first choice. Using your insurance for treatment, then letting your attorney deal with reimbursement and liens, may leave you with a smaller overall medical bill. Whether that works depends on your plan, your injuries and your case, which is a conversation to have with your attorney early.
How an LOP works step by step
- You are injured and need treatment. You tell the provider that you have an injury claim and have hired an attorney.
- Your attorney reviews the situation. A careful lawyer asks whether you have other ways to pay, what the provider charges and whether an LOP serves you.
- You give informed consent. Your attorney explains the risks and confirms your consent in writing.
- The letter is sent. The provider agrees to treat you and defer billing.
- Treatment continues while the claim develops. The provider tracks charges, and your attorney gathers records and bills as evidence.
- The case resolves. From the settlement or judgment, your attorney pays the provider the agreed amount, often after negotiating it down, then pays other expenses and fees. You receive the rest.
That last step is where the cost shows up. Every dollar paid to a provider comes out of your net recovery.
What an LOP can cost you
You are still responsible for the bill
This surprises many people. An LOP does not remove your personal responsibility for your medical bills. If the case ends with no recovery, or the settlement does not cover the full balance, you still owe what is left. The provider deferred collecting. It did not forgive anything.
Rates can be higher
Providers treating under an LOP may charge higher rates than those negotiated with insurers, so the total owed can grow substantially. A larger medical balance can reduce the money left for you.
Insurance companies may push back
The same source notes that insurers may scrutinize treatment provided under an LOP and argue it was driven by the lawsuit rather than medical need. That can affect how your claim is valued. Good documentation helps: consistent treatment records, clear links between the injury and the care, and reasonable charges.
Your attorney cannot simply walk away from it
Once a lawyer signs an LOP, the lawyer has an ethical obligation to honor it. If you later tell your lawyer not to pay the provider, the lawyer cannot resolve the dispute by handing you the money. The disputed portion stays in the attorney’s trust account until you and the provider agree or a court decides. This is not a lawyer being difficult. It is how the ethics rules work, and it is why you should not sign an LOP unless you are comfortable paying it.
Why a good lawyer treats the LOP as a conflict of interest
When your attorney promises a provider payment from your recovery, the attorney takes on an obligation to a third party. That can pull against the duty of loyalty to you. Under conflict-of-interest standards such as Utah’s rule on concurrent conflicts, the lawyer must explain the risks, including the effect on settlement proceeds, and obtain your informed consent, confirmed in writing, before proceeding.
Lawyer regulators have addressed the same issue elsewhere. Minnesota’s lawyer discipline office published a reminder about letters of protection, and an Ohio advisory opinion says lawyers should be transparent with providers. The letter should make clear that the attorney is not guaranteeing payment from the attorney’s own funds. The promise is to withhold settlement money to satisfy the debt.
What this means for you: a lawyer who hands you an LOP without a conversation about these points is not doing the job properly.
Letter of protection vs. lien
People use the two terms interchangeably, but they are different.
| Letter of protection | Lien | |
|---|---|---|
| What it is | A contractual promise | A legal claim on money |
| Who creates it | Attorney, patient and provider agree | Often arises by statute or by a court filing |
| Source of the right to payment | The contract | The law |
| Treatment tied to it | Treatment is deferred pending the case | Can attach after treatment, by law |
| Effect on your recovery | Provider is paid from settlement | Lienholder must usually be resolved before funds are released |
An LOP is a contractual promise, not a statutory lien, even though people often call it one. In Utah, other parties may also have claims against a settlement, including some hospitals and health plans. We explain how those work in our guide to Utah medical liens and Medicare recovery. An injury case can involve both an LOP and statutory liens, and your attorney needs to account for each before dividing the money.
Disclosure rules are changing
The rules about LOPs are not uniform across the country. As of 2026, Florida requires claimants to disclose the existence of an LOP, along with billing codes and any financial relationship between the law firm and the provider, in order to limit bias in testimony. That is a Florida statute and does not apply in Utah. But it shows where scrutiny is heading, and it is one more reason to keep your treatment records clean and your arrangements transparent, wherever your case is.
Questions to ask before you agree to an LOP
Bring these to your attorney before you sign or let a provider start treatment under one:
- Do I have another way to pay? Health insurance, medical payments coverage or workers’ compensation may cover some or all of the care.
- What does this provider charge? Ask whether rates are the provider’s full billed charges or an insurance-negotiated rate.
- Will the provider negotiate the bill at settlement? An agreement to reduce the balance, even if informal, can protect your net recovery.
- What happens if I lose or the case settles low? The honest answer is that you may still owe the balance.
- Is the provider recommending a certain lawyer or pressuring me to sign? Providers may ask patients to sign these on the spot. A better step is to ask the provider to contact your attorney first.
- Does the letter say my lawyer is not personally guaranteeing payment? It should describe a promise to withhold settlement funds.
What we think about LOPs
We come to this topic from the client’s side of the desk. Our firm has represented more than 1,300 clients and resolved more than 1,200 cases, and in injury work the conversation about paying for care is often the most stressful one. People are hurt, they are worried about work, and a clinic is willing to treat them now. That is a real relief, and we do not want to talk anyone out of care they need.
But we do not treat an LOP as paperwork. We ask whether insurance can pay first. We explain that the bill remains yours. We put the consent in writing. And we think about the end of the case from day one, because the settlement has to cover medical balances, any liens, fees and costs, and still leave you with something that makes a difference. Our contingency fee guide for personal injury shows how fees fit into that math.
No client should learn what an LOP means from the final settlement statement.

How an LOP fits into different injury cases
Car accidents
Car crash claims are the most common place people meet an LOP. Medical payments coverage may pay first, and then the question becomes what happens when it runs out. The way treatment bills are handled can affect your final number, as we describe in our article on protecting a Utah car accident settlement. If the at-fault driver is uninsured, there are different deadlines and coverage questions, covered in our guide to the Utah uninsured motorist claim.
Work injuries
If you were hurt on the job, workers’ compensation is normally the route for medical care, and it works differently from an LOP. Where a third party caused the injury, a separate claim may exist. See our overview of third-party work injury claims in Utah before agreeing to any deferred-payment arrangement for treatment.
Other personal injury claims
Falls, dog bites, defective products and wrongful death claims can all involve deferred-payment treatment. If you want to see what kinds of matters injury lawyers take on, a general overview of personal injury case types is a good starting point.
Working with us
If you have been injured in Utah and are weighing how to pay for treatment, we can review your situation, explain whether an LOP makes sense and help you understand the effect on your recovery. Our Salt Lake City personal injury team handles injury claims, and you can see everything else we do on our practice areas page. We do not publish fees on our site, so ask about the fee arrangement for your case at the first conversation.
FAQ
Is a letter of protection the same as a lien?
No. An LOP is a contractual promise made among you, your attorney and a provider. A lien is a legal claim on money, often created by statute. A single case can involve both, and each has to be paid or resolved before you receive your share.
Do I have to pay the doctor if I lose my case?
Often, yes. An LOP does not erase your personal responsibility for the bill. If the case brings no recovery, or too little, you may still owe the balance. Some providers will agree to reduce or write off bills, but you should not count on that unless it is in writing.
Can any provider be paid through an LOP?
Only a provider that agrees to the arrangement. Many providers accept them in injury cases, but some do not, and the terms vary. Ask your attorney to confirm the terms with the provider before treatment starts.
Can my attorney sign an LOP without my permission?
No. Because the LOP creates a conflict of interest, your lawyer must explain the risks and get your informed consent, confirmed in writing. If you have not had that conversation, ask for it before treatment continues.
Can I cancel an LOP after signing it?
You can tell your attorney you object, but that does not make the obligation vanish. Once signed, the attorney must honor it, and any disputed money is held in the trust account until you and the provider settle it or a court decides.
