Maryland law says that you have to file a document called an "affidavit" along with your motion or response. A contract consists of a legally binding agreement or promise between parties.The court requires proof of service. The person who served the documents should fill out an affidavit of service. This form must be completed and filed when you file any court documents that contain restricted information. Maryland Notary instructor Elaine Wright Harris explains what to do when Notaries in her state encounter documents that do not include certificate wording. The Comptroller's office will also not accept a Form MD 433-A without a Form MD 656, Offer in Comptroller Application. If, when filling out an application, a landlord asks for money to hold an apartment, it may not be clear that you are being asked for a security deposit. Both commercial and residential properties in the City of Rockville are required to obtain permits before starting construction projects. Next print the form and then fill in the required responses.
