What Does a Home Insurer's Special Investigation Unit Do?
It investigates claims that look unusual, such as possible fraud, arson, or inflated losses, before the insurer pays.

Why a claim gets flagged
SIU referrals usually start with a pattern. Claims filed soon after a policy starts, damage that doesn't match the reported cause, prior losses at the same address, or inconsistent statements can trigger a referral. One flag rarely sinks a claim, but several together often do.
What the review involves
Expect requests for a recorded statement under oath, bank and contractor records, and permission to pull your claim history. An investigator may re-inspect the property or hire a forensic engineer. None of this means fraud is assumed. It means your file needs more documentation before payment.
How it changes your timeline
Most states let insurers pause the normal claim deadline while investigating, as long as they tell you it's happening. Your claim can sit for weeks or months longer than a routine one. Ask the adjuster directly whether your file has been referred to SIU, since that explains the delay.
If you disagree
An SIU review can end in a denial, a reduced payout, or a required examination under oath. Your denial letter states the reason and your state's appeal window. You can also dispute the amount through appraisal if your policy allows it.

An SIU review doesn't change what your policy owes you, only how long it takes to get there and how well your records hold up under questions. If the payout still looks short once the investigation closes, or the denial doesn't match your documentation, comparing your policy's language against other coverage options can show whether the settlement reflects what you're actually owed.
What to do if you're asked for an examination under oath
An examination under oath is different from the recorded statement you may have already given. It's a formal, transcribed interview, usually with the insurer's attorney present, and you answer questions under oath the same as in a courtroom. Your policy requires you to sit for one if asked. Refusing can be treated as a breach of the policy and used to deny the claim outright, so this isn't something to skip or put off.
You're entitled to bring your own attorney, and for a claim that's reached this stage, it's worth having one. The insurer's attorney will ask about the cause of loss, your finances, prior claims, and anything inconsistent in what you've already said or submitted. They have your claim file, your statements, and often your financial records in front of them. Answer what's asked, stick to what you know, and don't guess at details you're unsure of. Guessing wrong is how small inconsistencies turn into bigger problems.
Before the exam, go back through everything you've already told the insurer. Reread the initial claim report, any recorded statement, receipts, and repair estimates. If dates or numbers don't line up, you want to know that before the insurer's attorney points it out. Bring your own copies of documents you've submitted so you can reference them instead of relying on memory alone.
The exam itself doesn't end the claim. The insurer reviews the transcript along with everything else in the file before deciding to pay, deny, or settle for a reduced amount. If the outcome still doesn't match your documentation afterward, your denial or payout letter will lay out your state's appeal window and whether appraisal is available under your policy. Nothing said in the exam changes what your policy actually covers. It only affects whether the insurer is satisfied the claim is legitimate as filed.

How long can an SIU investigation take
There's no fixed deadline for an SIU investigation. Most states require insurers to acknowledge your claim and begin investigating within a set number of days, often 15 to 30, but once a claim is referred to SIU, those routine deadlines often pause. The insurer still has to notify you that the investigation is ongoing, and that notice should come periodically, not just once at the start. If you haven't heard anything in over a month, you're entitled to ask for a status update.
What drags a case out is usually the recordkeeping, not the suspicion itself. Subpoenaing bank records, scheduling an examination under oath, waiting on a forensic engineer's report, each step adds weeks. A straightforward claim might clear SIU review in a month. One involving a fire, a public adjuster, or a prior loss at the same address can take several months before the insurer reaches a decision.
Ask your adjuster for a rough timeline even if they can't give you an exact date. Insurers are required to explain why a claim is delayed if you ask directly, and getting that in writing gives you something to point to later if the delay stretches on without explanation. Keep a log of every call and letter, including dates, so you have your own record if the claim drags past what seems reasonable.
If the investigation closes and you disagree with the outcome, the clock resets in your favor. Your state sets a window for filing an appeal or a complaint with the insurance department once you receive a denial or a reduced payout, and that window is usually spelled out in the letter itself. A long SIU review doesn't shorten that window. It just means the decision took longer to reach.

Before you answer anything
Pull your declarations page and every statement, receipt, and estimate you've already submitted, and check them against each other for dates or numbers that don't match before you say another word to the insurer.
