Seller Disclosure for Damage History: What's Required
Last updated October 25, 2026
The short answer
Know Your State's Rules
Each state sets its own rules for what a home seller must disclose. Some states require a detailed form with specific questions about water damage, while others have broader requirements. You need to check your state's real estate disclosure laws to know exactly what applies to you. A qualified attorney or your local real estate association can point you to the right form.
In general, you must disclose any known defect that affects the property's value or safety. Water damage, mold, and foundation issues are common examples. If you are unsure whether a past issue counts, it is safer to disclose it. Hiding a known problem can create legal exposure after the sale.
What Counts as Damage History
Damage history includes any past water intrusion, flooding, plumbing leaks, or roof leaks that caused visible damage or required repairs. It also includes mold growth, even if you cleaned it, and any structural repairs made after water damage. You need to disclose issues that are still present or that you know about, even if they were fully repaired.
If you had a leak that was fixed and shows no signs of a problem, you still need to disclose it if your state's form asks about past damage. Some buyers care about history because it can indicate future risk. Be honest and specific about what happened and what you did to fix it.
- Past roof leaks and repairs
- Plumbing leaks in walls or floors
- Flooding from storms or burst pipes
- Mold or mildew issues and remediation
- Foundation cracks from water damage
- Any insurance claims you filed for water damage
Disclosure Forms and Timing
Most states require you to complete a seller disclosure form before the buyer makes an offer or soon after. The form asks about known defects and past damage. You need to answer every question truthfully. If you don't know an answer, it is acceptable to write 'unknown' rather than guess.
You must provide the form before the sale closes, but the timing can vary. In many states, the buyer can back out if they receive a disclosure that reveals undisclosed problems. Check your state's rules or ask a qualified attorney to confirm the deadline for your situation.
Disclose Even If Repaired
Repairing damage does not erase your obligation to disclose it. The law focuses on what you know, not on whether the issue is fixed. If you had a water leak that you repaired, you still need to mention it on the disclosure form. The buyer has a right to know about the history, even if the current condition is good.
Some sellers worry that disclosing will scare off buyers. In reality, honest disclosure can build trust and avoid disputes later. If you hide a past issue and the buyer discovers it after closing, they may have legal grounds to sue you for nondisclosure. It is better to be upfront from the start.
When to Get Professional Help
If you are unsure about what to disclose or how to answer a question, consult a qualified attorney who handles real estate transactions. They can review your situation and help you complete the form correctly. You might also consider having a water damage inspection done before you sell, so you know the current condition and can address any issues.
If you live in Kirkland, the mild marine climate with wet winters and dry summers can make water damage a concern for homes. A professional inspection can reveal hidden issues that you might not know about. This helps you disclose accurately and gives buyers confidence. Even if you are not in Kirkland, a pre-sale inspection can be a smart step. Policies vary, and your insurer decides what is covered.
- Hire a qualified attorney to review your disclosure form
- Consider a pre-sale water damage inspection to identify issues
- Keep records of any repairs or remediation you have done
- Ask your real estate agent for guidance on local rules
- Do not rely on verbal assurances from buyers or agents

What happens if I fail to disclose water damage?
If you fail to disclose a known issue and the buyer later discovers it, they can take legal action. You may be liable for repair costs, legal fees, and other damages. In some cases, the sale can even be rescinded. Always disclose known issues to protect yourself.
Do I need to disclose a past leak that was fully repaired?
Yes, if your state's disclosure form asks about past water damage, you need to disclose it, even if the repair was complete. The buyer has the right to know about the history. If you are unsure, check the form or ask a qualified attorney.
Can I write 'unknown' on the disclosure form?
You can write 'unknown' if you genuinely do not know about a problem. However, you cannot use it to avoid answering. If you know about damage, you must disclose it. Writing 'unknown' when you actually know is a form of fraud.
