What Is California Labor Code §5100: Lump-Sum Commutation?

At the time of making its award, or at any time thereafter, the appeals board, on its own motion either upon notice, or upon application of either party with due notice to the other, may commute the compensation payable under this division to a lump sum and order it to be paid forthwith or at some future time if any of the following conditions appear: (a) That such commutation is necessary for the protection of the person entitled thereto, or for the best interest of the applicant.

What does Labor Code 5100 mean by commutation?

Commutation means converting a benefit that would normally be paid over time into one payment made now.

Most California workers' comp benefits are paid periodically: a weekly temporary disability check, a weekly permanent disability check, or, for some injuries, a life pension paid for the rest of a person's life. This law lets a workers' compensation judge order some or all of that future stream paid out as one lump sum instead. It applies to a benefit already awarded, or being paid, under an open claim. It is a tool a judge can use after an award exists, not a separate kind of claim.

Who can ask for a lump sum, and when?

Either side can ask, with notice to the other side, and the judge can also raise it without being asked.

A request can be made at the time of the award or at any later point while benefits are still being paid. The worker, the employer, or the insurer can file the request. The other side must get notice and a chance to respond. The judge decides the request; it is not something a claims adjuster can grant on their own.

What conditions let a judge order commutation?

The statute lists four situations, and only one needs to be true.

The law allows commutation when a lump sum is necessary to protect the worker, or otherwise fits the worker's best interest. The judge weighs the worker's overall finances and ability to live without the regular checks. The law also allows commutation when a lump sum would avoid unfairness without undue hardship or expense for the worker. The same is true when the employer has sold off most of its assets, is about to, or does not live in California. A judge checks the actual facts of the case against these conditions before ordering a lump sum.

How is the lump-sum amount calculated?

The math depends on whether the benefit is temporary disability, permanent disability, or a death benefit.

Under Labor Code section 5101, the board estimates how many more weeks of temporary disability payments are likely, then sets the lump sum at that total. For permanent disability or a death benefit, the board fixes the full amount still owed. It then reduces that amount to its present value, assuming 3 percent yearly interest. If the disability rating is high enough to carry a life pension, the board also factors in the worker's life expectancy when it values that part of the award.

PD rating	Benefit weeks	Award at the 2026 max ($290/wk)
10 percent	30.25 weeks	$8,772.50
20 percent	75.5 weeks	$21,895
30 percent	131 weeks	$37,990
40 percent	201 weeks	$58,290
50 percent	271.25 weeks	$78,662.50
60 percent	351.25 weeks	$101,862.50
70 percent	433.25 weeks	$125,642.50 plus a life pension

Is commutation the same thing as a settlement?

No. A settlement resolves the claim itself; commutation only changes how an existing award gets paid.

A Compromise and Release is a negotiated settlement that closes out a claim, often including future medical care. It needs its own judge-approved order before it is final. This page explains that approval order. This kind of commutation is different. It takes a benefit that has already been awarded, such as a permanent disability payment or a life pension. It changes the payment schedule, not the underlying claim. The section 5101 calculation covers temporary disability, permanent disability, and death benefits. It has no method for valuing future medical care, so commutation is not the usual way to close out medical treatment rights. A worker who wants to resolve future medical along with the rest of the case typically does that through a negotiated settlement instead; this page covers when an insurer puts a settlement on the table.

What should a worker save or ask before requesting a lump sum?

Bring the actual award, a clear reason tied to one of the four conditions, and a realistic picture of what living without the weekly check will look like.

Keep a copy of the award or stipulation that created the ongoing payments. Be ready to explain, in concrete terms, why a lump sum protects the worker's interest. One example is paying off a debt that predates the injury. Another is covering a specific, documented need. A judge weighs the worker's full financial picture, so a vague request carries less weight than a clear, documented reason.

Have the award paperwork and a clear statement of why a lump sum is needed ready to discuss. A workers' comp attorney in California is usually paid a share of the benefits recovered, often in the 15 to 18 percent range, and a workers' compensation judge must approve that fee under Labor Code section 4906 before it is paid.
