NH Law About... Security Deposits

Introduction to... Security Deposits

Updated May 23, 2017.

Most of the questions we receive at the law library about security deposits deal with RSA 540-A, Prohibited Practices and Security Deposits. Not every residential tenancy is protected under this law so review the New Hampshire Legal Aid information on security deposits (below) carefully. The website explains who is protected, the maximum security deposit a landlord can charge, interest on security deposits, and what happens if your landlord files for bankruptcy or is in foreclosure. 

If your landlord is refusing to return a security deposit, or you're a landlord who is being sued for the return of a security deposit, review the information on the Small Claims website.  The website links to the statute governing Small Claims, RSA 503, applicable court rules and other information. 

Legal Research Note

There's one thing you might find confusing if you are using the online version of the statutes to research security deposits in manufactured housing parks. Security deposits are mentioned under RSA 205-A, Regulation of Manufactured Housing Parks. As of this writing, that statute still refers you to RSA 477:48. If you then go to RSA 477:48, you will find that that section was repealed in 1985. The online version doesn't give you any hints as to what to do next. The print version of RSA 205-A, however, has an editor's note explaining the repeal and directing researchers to RSA 540-A which, after 1985, includes manufactured housing. We won't go so far as to say that this type of error is common in the statutes, but we've seen similar things often enough that we are no longer surprised. Amending statutes is a complicated process and, every once in a while, you will see errors like this one. Editorial notes explaining that explain these types of things are one reason why we still link to libraries that own the print statutes instead of just providing links to online versions.
