WHY THIS WORKS

It cites the exact regulation the plan is bound by, not "the law". A reviewer escalates a letter that names the rule and the standard of review.

29 CFR § 2560.503-1
IT DEMANDS SPECIFIC THINGS

Numbered requests create a paper trail. The reviewer's credentials and the plan provision relied on are both things the plan is required to produce.

IT SETS UP THE NEXT STEP

The closing names external review and the civil remedy that follow if the plan ignores it. That is what changes behavior.

45 CFR § 147.136(d)

Common questions.

Is this legal advice?

No. Explicitly not. FightThis is a drafting tool. We help you write a letter you could write yourself with enough time and research. We do not review your case for legal merit and we do not represent you. For high-stakes situations, hire an attorney. Read the full disclaimer.

Do I need an account to see the draft?

No. Upload the notice, answer a few questions, and a watermarked preview of the draft appears. After payment we create a magic-link account tied to your email so you can get back to your letters. No password.

What if the letter gets something wrong?

Read it carefully before you send it; you are responsible for the contents. If the quality misses the mark, request a free redraft from your account dashboard within 14 days of delivery. We respond within 24 hours and deliver the redraft, typically within 24 to 48 hours. Refund requests are reviewed individually. Refunds and redrafts.

How long does drafting take?

Usually a minute or two, longer for long or scanned notices. You see progress while you wait, and you can correct anything the document reader misread before the letter is written.
