Why this local filing matters
The official label is Business Certificate, the local entity branch includes sole proprietors and general partnerships, and the clerk’s supported fee is thirty-five dollars.
Official destination title: Westchester County Clerk
It also contains two distinct post-filing rules that the Texas records here do not share: an amended certificate tied to inaccurate facts or a thirty-day change period, and a certificate of discontinuance filed where the original was lodged.
Whenever a filed certificate no longer accurately states the required facts, or within thirty days after a change, an amended certificate shall be filed.
If the business is discontinued, a certificate of discontinuance may be filed with the county clerk with whom the original certificate was filed.
