Who must sign the "Owner's Certificate" on the plat?

The "Owner's Certificate" on a plat must be signed by the Owner(s) of record and a Notary Public to ensure the authenticity and legality of the signatures. The owner's signature is required to certify that they acknowledge the plat and consent to its filing, while the Notary Public provides a formal verification by witnessing the signing of the document and affirming the identity of the signers. This process protects both the property owner and the public by ensuring that the information on the plat is accurately represented and legally binding.

Other roles, such as those of a surveyor, local engineer, City Council, County Clerk, architect, or city planner, while integral to different aspects of the surveying and city planning processes, do not hold the requirement of signing the Owner's Certificate, making this specific combination of signatures necessary for the validity of the plat.
