The County Clerk's office now offers poly envelopes for the protection of your important documents. These envelopes are non-migratory, guaranteeing that the ink will not come off on the envelope and they are clear which makes it easy to find your documents. They come in two (2) sizes: letter and legal. Both are available for $2.00 each and can be purchased at the following County Clerk Offices: Travis Building in Richmond; North Annex in Katy, and East Annex in Missouri City.
