A pension lawyer handles disputes between you and your pension plan, helps you recover money the plan owes you, and represents you in appeals when benefits are denied
Pension lawyers work on cases involving employer retirement plans, union pensions, and government pensions. They do not help you choose investments or plan for retirement — that is a financial advisor's job. Instead, they step in when something has gone wrong: your plan denied a benefit you believe you are owed, your employer stopped funding the plan, you were fired before vesting, or the plan administrator made an error in calculating your benefit amount.
Most pension lawyers work on contingency, meaning they take a percentage of the money they recover rather than charging you an hourly fee upfront. This matters because pension cases are expensive to litigate, and a lawyer will only take your case if they believe they can win money back. If your case has no financial recovery attached — for instance, you just want to understand your plan documents — you may need to pay hourly fees instead.
Key Takeaways
- Pension lawyers represent you in disputes with your plan administrator, usually when benefits are denied or calculated incorrectly.
- Most work on contingency, taking a percentage of recovered money rather than charging upfront fees.
- They handle appeals within the plan first, then file lawsuits in federal court if the plan denies your appeal.
- You may also need a pension lawyer if your employer stops funding the plan or if you believe the plan violated federal pension law.
- Finding one usually means contacting your state bar association or a legal aid office that handles pension cases.
When a pension plan denies your benefit claim
When a plan administrator denies your request for benefits, federal law requires them to give you a written explanation of why. This explanation is your starting point. A pension lawyer will read it, compare it to your plan documents and work history, and tell you whether the denial was correct under the plan's rules.
If the lawyer believes the denial was wrong, they will file an appeal with the plan. This is a formal written challenge that must follow strict deadlines — usually 60 days from the denial letter. The plan then has 60 days to respond. If the plan upholds the denial, your lawyer can file a lawsuit in federal court. Federal courts handle pension disputes under a law called ERISA (the Employee Retirement Income Security Act), and the standard is whether the plan administrator abused their discretion in denying you.
The appeal process itself does not require a lawyer — you can file one yourself. But having a lawyer increases your chances of success because they know how to frame your argument in legal terms and how to cite the plan documents correctly. Many people file appeals on their own, lose, and then hire a lawyer to sue.
Disputes over how your benefit was calculated
Pension plans use formulas to calculate your monthly benefit. A common formula is: years of service multiplied by a percentage of your average salary. If you believe the plan used the wrong salary figure, counted the wrong years, or applied the wrong percentage, a pension lawyer can audit the calculation.
These cases often turn on what the plan documents actually say. For example, does "average salary" mean your last three years, your last five years, or your highest-earning years? Did the plan count unpaid leave as service time? Was a bonus included in salary? A lawyer will pull your personnel file, your plan documents, and the plan's calculation worksheet, then compare them line by line.
If the calculation was wrong, the plan owes you the difference between what you received and what you should have received, usually with interest. This is money your lawyer can recover, which is why these cases are often taken on contingency.
Vesting disputes and early termination
You are vested in a pension when you have worked long enough that the money belongs to you permanently, even if you leave the job. Vesting schedules vary — some plans vest after five years, others after ten. If you were fired or laid off before vesting, you may lose the entire pension benefit.
A pension lawyer can challenge whether your employer had a legal reason to terminate you before vesting, or whether the plan correctly applied its vesting schedule to your situation. For instance, some plans count military service or unpaid leave toward vesting time, and employers sometimes fail to include these periods. A lawyer will review your employment agreement, the plan documents, and your service record to see whether you actually were vested.
These cases are harder to win on contingency because there is no money to recover if you were not vested — you either are or you are not. Some lawyers will take them on an hourly basis if they believe you have a strong case.
Plan terminations and underfunded pensions
When an employer stops funding a pension plan, or when a plan does not have enough money to pay all promised benefits, a pension lawyer can help you understand your rights. If the plan is insured by the Pension Benefit Guaranty Corporation (PBGC), a federal agency, your benefit may be protected up to a legal limit. That limit changes each year — in 2024 it was around $5,000 per month for someone age 65, but it is lower for younger retirees and higher for some others.
A lawyer can file a claim with the PBGC on your behalf, appeal if the PBGC denies your claim, or sue the plan sponsor if they violated pension law by underfunding the plan. These cases are complex and often involve multiple retirees, sometimes resulting in class action lawsuits.
How to find a pension lawyer
Start with your state bar association's lawyer referral service. Most state bars have a section for employment law or benefits law, and they can give you names of lawyers who handle pension cases. Ask whether they work on contingency and what percentage they take — this usually ranges from 20 to 33 percent of recovered money.
If you cannot afford a lawyer, contact your local legal aid office. Some legal aid programs have pension specialists, though many do not because pension law is specialized. You can also call the National Pension Lawyers Network or search the American Association for Justice's directory of lawyers who handle pension cases.
When you call, be ready to describe what happened: Was your benefit denied? Was it calculated wrong? Were you fired before vesting? Have you already filed an appeal? Lawyers will want to know whether you still have time to appeal under the plan's deadlines, because missing a deadline can close your case permanently.
What a pension lawyer cannot do
A pension lawyer cannot force your employer to create a pension plan, increase your benefit, or change the plan's rules. They also cannot help you withdraw money early, take a lump sum instead of monthly payments, or negotiate a settlement with your employer — those are decisions you make, sometimes with a financial advisor's help.
Pension lawyers also do not handle Social Security, 401(k) plans, or individual retirement accounts (IRAs). Those are different legal areas with different rules. If your dispute involves a 401(k) or IRA, you need a lawyer who specializes in that area, though the process is similar: appeal first, then sue in federal court if the appeal fails.
Frequently Asked Questions
How much does a pension lawyer cost?
Most work on contingency, taking 20 to 33 percent of money they recover. You pay nothing upfront and nothing if you lose. If your case does not involve money recovery — for instance, you just want to understand your plan documents — you may pay hourly fees, which vary by location and lawyer experience but typically range from $150 to $400 per hour.
How long does a pension case take?
The appeal process inside the plan usually takes 60 to 120 days. If you then sue in federal court, the case can take one to three years, depending on whether it settles or goes to trial. Some cases settle faster once a lawsuit is filed because the plan realizes it will lose.
Can I sue my employer directly instead of the plan?
In most cases, no. Federal pension law requires you to exhaust the plan's appeal process first. You can only sue the plan administrator or the plan itself. You can sue your employer separately if they violated a contract or discriminated against you, but that is a different kind of case handled by an employment lawyer.
What if I already received my pension — can I still hire a lawyer?
Yes, if you believe the calculation was wrong or the plan made an error. You can recover the difference between what you received and what you should have received, usually with interest. You will need to file an appeal within the time limit set by your plan, which is typically 60 days from when you discovered the error.
Do I need a lawyer to file an appeal?
No, you can file an appeal yourself. But having a lawyer increases your chances of success because they know how to frame your argument correctly and cite the plan documents. Many people file appeals on their own, lose, and then hire a lawyer to sue in court.
