If you have been served
Note the date and manner of service, because the time to respond depends on how you were served, and missing it risks a default judgment. Check whether a notice of pendency was filed against your property, which can complicate a sale or refinance until it is resolved. Look at your title insurance policy and any homeowner's or liability policy, since some claims are covered and insurers usually expect prompt notice. Do not transfer the property or move assets in response to the lawsuit without advice, because that can create new claims against you. If co-owners or a spouse were named as well, decide early whether you can share a lawyer or need separate ones.
If you are considering suing
Before filing, it helps to know which claim fits the facts, because a failed closing, a construction defect, and a boundary encroachment each call for different relief and sometimes different courts. Limitations periods vary by claim, so the date the problem began matters. A demand letter often comes first and can resolve smaller disputes without a filing. If the contract has an arbitration clause, a forum selection clause, or a provision on legal fees, those terms shape where and how the case would proceed. If the other side is a government body, a notice requirement with a short deadline may apply before any lawsuit can be filed.
Records to lock down now
Whichever side you are on, gather the contract, deed, closing documents, survey, inspection reports, and all correspondence, including texts. Do not delete messages or social media posts that touch on the dispute. If physical conditions matter, photos and video taken now may be the clearest record later, provided you can take them without entering property you are not allowed on. Our first meeting is about the deadlines, the insurance question, and whether a negotiated path exists before litigation costs climb. We also talk about who else should be told about the case, such as a lender or co-owner, and who should not.
