If your long-term disability, life, health, or other employee benefit claim was denied under ERISA, the appeal stage is often the part of the case that matters most. Many people assume the real fight happens later, in court. In general terms, ERISA cases often work differently. By the time a lawsuit is filed, the judge may spend most of the case looking at the administrative record that was built during the claim and appeal process, not brand-new evidence gathered afterward. The U.S. Supreme Court has noted that claimants who do not develop evidence during internal review risk losing the ability to use that evidence later, and many federal courts limit review to that record.

In this post you’ll learn how to build an ERISA appeal record, what kinds of evidence often matter, how the deadlines work, and why timing can be as important as substance. If you want a broader overview of the internal review process, this deeper guide on how ERISA appeals and the administrative record usually work can help frame the bigger picture.

ERISA requires covered plans to provide a reasonable claims procedure and a full and fair review of denied claims. The Department of Labor’s claims-procedure regulation lays out the minimum rules plans generally follow, including notice requirements, access to relevant documents, and appeal rights.

Here’s what this often means in practice:
That structure is one reason ERISA appeals are different from ordinary civil litigation. In a typical lawsuit, people often expect witness testimony, discovery, and new expert opinions later on. In many ERISA benefit cases, especially when deferential review applies, the dispute can turn heavily on what was already placed in the claim file before the final appeal decision. The Supreme Court’s ERISA cases on standard of review, including Firestone Tire & Rubber Co. v. Bruch and Metropolitan Life Insurance Co. v. Glenn, help explain why the administrative process carries so much weight.
The first thing to pin down is the plan’s appeal deadline. Under the Department of Labor’s ERISA claims rules, group health plans and disability plans have specific minimum procedural requirements, but the actual notice of denial and plan documents often control the precise deadline for a particular appeal.

For disability claims, the Department of Labor explains that an appeal generally must be decided within a reasonable period, and no later than 45 days after the plan receives the appeal, with limited extension rules in some situations. U.S. Department of Labor disability benefits claim filing guide; 29 C.F.R. § 2560.503-1(i)(3)
For many non-disability benefit claims, the regulation generally provides a 60-day period for a decision on review, again subject to the rule’s details and exceptions. 29 C.F.R. § 2560.503-1(i)(1)
The key point is not just when the appeal is due, but when the evidentiary window may start closing. Some people view the appeal as a short letter saying “please reconsider.” In many ERISA cases, the appeal is closer to the claimant’s best chance to present the complete factual, medical, vocational, and plan-based case.
Before drafting the appeal, it often helps to know what the insurer already has, what it relied on, and what the plan language actually says.
The Department of Labor states that claimants are entitled, upon request and free of charge, to relevant documents, records, and other information relating to the benefit claim. U.S. Department of Labor guide to filing claims and appeals; 29 C.F.R. § 2560.503-1
