Bill Single Law and Legal Definition
Bill single is a written promise to pay, executed under the seal of the maker. It is a promise by which, one person or more, promises to another or others, to pay him or them a sum of money at a time therein specified, without any condition. It differs from a promissory note in this, that the latter is always payable to order; and from a bond, because that instrument has always a condition attached to it, on the performance of which it is satisfied.
A bill single is also known as promissory note under seal. The obligor having a good title and conveying an equitable right would be a sufficient consideration for a note or bill single. [Montgomery v. Dillingham, 11 Miss. 647 (Miss. 1844)].
