Once an enrolled bill or concurrent resolution is signed by the governor, or the governor allows a bill to become a law without a signature, the executive clerk to the governor forwards the bill or resolution to the Office of the Secretary of State (SOS), where it is considered "filed" once the secretary of state signs it. A joint resolution is not submitted to the governor for signing and is filed directly with the secretary of state. Official signed copies of enacted bills and resolutions can be viewed online at the Secretary of State's website.

On filing, the original signed bill or resolution and a copy are sent to the SOS Statutory Documents Section. There, the original signed documents are microfilmed and sent to be bound. The bound documents are stored at the Texas State Library and Archives Commission. Copies of enacted bills and joint and concurrent resolutions are compiled, certified, and sent to Thomson West for inclusion in the General and Special Laws of the State of Texas, also called the "session laws." SOS staff assign a session law chapter to each enacted bill based on the date the bill is filed with the secretary of state; bills that are filed on the same date are placed in chronological bill number order for chapter number assignment. The Texas Legislative Council and Thomson West incorporate the changes made by enacted bills into their compilations of Texas statutes and codes.
