Suffolk County Clerk
At one time or another either directly or
indirectly, every resident of Suffolk County deals with our office. So if you are buying
home, satisfying your mortgage, filing a lien or judgment, grieving your taxes or
interacting with the judicial system, we look forward to working with you.
If there are any changes to the business after a business certificate has been filed with the County Clerk, you must file an Amended Business Certificate for Individual form if a sole proprietorship or an Amended Business Certificate for Partners form for a business conducted as partners with more than one filer.
An original of the Amended Business Certificate must be submitted within 30 days of the amendment.
If the amended certificate is filed for the purpose of adding or withdrawing a partner named in the original certificate, such amended certificate must be executed by such person and by any one or more of the other persons named in the original or last amended certificate, unless otherwise provided by an order of the Supreme Court, Suffolk County.
Any other amended certificate may be executed by any one or more of the persons named therein: as a person conducting the business, as a partner, or in the case of a corporation, by an officer of the corporation.
Payment may be made in the form of Personal Check, Certified Bank Check, Money Order and Attorney’s Check made payable to the Suffolk County Clerk.
Any returned check incurs a $20.00 fee.
When submitting a Business Certificate also include a self- addressed stamped envelope.
