Contingency percentages, hourly retainers, section 502(g) fee awards and how past-due benefits are counted, and the clauses a careful reader checks before signing.

Most group long-term disability policies reduce the monthly benefit by any Social Security disability award, applied retroactively to the date that award began. That reduction can shrink a past-due total substantially.
The fee agreement usually arrives as three or four pages, and it is the first document in the whole dispute that the claimant actually controls. Everything before it, the plan booklet, the denial letter, the deadline printed in the second paragraph, was written by somebody else. The agreement is negotiable in ways most people assume it is not, and the terms inside it decide who carries the cost of losing, what a win is worth after the deduction, and whether the money arrives in one lump or over years. Reading it slowly is worth the hour.
Most long-term disability appeals and lawsuits are taken on contingency, because the claimant has usually lost the income the fee would otherwise come from. The headline percentage matters less than its base. A careful reader checks whether the fee is calculated on past-due benefits only, on past-due plus some measure of future benefits, and whether it is figured before or after the offset for Social Security Disability Insurance, which most group policies apply retroactively. A percentage of the gross monthly benefit and a percentage of the net after offset can differ by half, on the same claim, with the same result.
Past-due benefits themselves are a calculation, not a fact sitting in a file. The count usually starts at the date benefits should have resumed under the policy, runs to the date of settlement or judgment, and is multiplied by the monthly benefit stated in the plan. Every offset the plan is allowed to take, Social Security, workers' compensation, other disability income, reduces that figure. So does any period the insurer argues was outside the elimination period. Ask, in writing, what the estimated past-due figure is and which offsets have been assumed.
Contingency does not suit every question. Plan interpretation work, reading a pension document to establish which benefit formula applies, checking whether a health plan's exclusion reaches a particular treatment, advising a participant deciding between two elections, produces no pot of past-due money to take a share of. That work is normally billed hourly against a retainer, and the retainer is a deposit, not a fee. What a careful reader checks is the billing increment, the rate for paralegal and associate time, whether the unused balance is refundable, and what triggers a request for a replenishment.
Some engagements are hybrid, and that is not a red flag by itself. A firm may bill hourly to review the plan and the denial, then convert to contingency if it takes the appeal. The clause worth finding is the one describing what happens at the switch: whether the hours already billed are credited against the eventual contingency fee, or sit on top of it. Costs are separate again. Independent medical opinions, vocational reports, court filing fees and record copying are usually advanced by the firm and repaid from recovery, and the agreement should say whether repayment comes off the top or after the fee.
Federal benefits law gives a court discretion to award reasonable attorney's fees and costs to either party in an action to recover plan benefits. The Department of Labor is responsible for the rules governing employee benefit plan claims and appeals, and the fee provision sits alongside them in the same statute. Discretion is the operative word. There is no automatic entitlement, no fixed formula, and courts weigh factors including the losing party's culpability, its ability to pay, and whether an award would deter similar conduct. A claimant who achieves some success on the merits may ask.
Because the provision is symmetrical in text, an insurer or plan can in principle seek fees against a claimant, though in practice awards run overwhelmingly the other way. The agreement should still address it. What a careful reader checks is what happens to a court-awarded fee: whether it is credited against the contingency percentage, so the client keeps more, or whether the firm keeps both. Firms differ, both approaches exist, and neither is hidden. It simply has to be asked about before signing rather than after the check clears.
Two more provisions repay attention. The first covers withdrawal and discharge: what the firm is owed if the client ends the relationship midway, and whether that is measured in hours worked or a share of any later recovery. The second covers settlement authority, and whether a lump-sum buyout of future benefits, which insurers frequently propose, counts toward the fee base. A firm willing to walk through both, slowly, and to put its estimate of past-due benefits on paper, is telling the reader something useful about how the rest of the case will run.
