If a person fails to get a deed to a property that they claim adverse possession on what happens?

If a person fails to obtain a deed to a property they claim under adverse possession, they do not gain legal ownership of the property. Their claim may lead to disputes with the true owner, who can assert their rights and reclaim possession. The claimant's investment or improvements made to the property may not be compensated, and they may have to vacate the property if the rightful owner enforces their rights. Ultimately, without a successful legal claim, the person retains no legal interest in the property.
