Great penmanship may be an asset in many walks of life, but it can be a decided disadvantage at a real estate closing, especially if one party to the transaction has pre-signed.
Then, the closer must determine that there’s an exact match between the absent party’s signature, and the document authorizing a representative to sign for them (typically, a limited power of attorney).
When the signature is sloppy, it’s harder to tell if there’s a discrepancy.
