Under Texas law, you have a right to have a copy of your guardianship paperwork. To establish a guardianship, you must retain an attorney, preferably one with experience in the field.Can I request a certified copy for the court order of the legal guardianship I am under if I am underage? This guide includes forms and instructions for a letter and affidavit to request that the court register an outofstate custody order in Texas. Each guardianship program must renew the registration on or before its expiration in order to continue to offer or render guardianship services. You may call the County Clerk at (361)361-9350 to request issuance of letters. These forms and instructions are available in the General Clerk's Office, Room 108, in the Nassau County. To complete this investigation, the Court appoints a Guardian Ad Litem (GAL). Guardianships in Texas differ a lot from custody. The Instructions for Completing the Orders – currently under the Temporary Ex Parte Order form – apply to all orders, including the MOEP.
