In general, it may be stated that anyone who has legal capacity to enter into a contract, may bind himself on his contract to answer for the debt, or default of another, and in general it may be said the party may be considered incompetent to bind himself as a surety, where his ordinary contracts would be either void or voidable. The promissor in suretyship must not be of unsound mind, or be under the lawful age to contract, and at common law the fact that the promissor was a feme covert, that is a married woman, would disqualify her from making a binding contract of suretyship, so also the usual rule of partial disability of the partnership, and the corporation to contract generally, would prevail in the matter of their ability to answer for the debt, or default of another. In addition to the common law disability there exists in certain states, the statutory rule that certain other persons, such as attorneys-at-law shall not be proper sureties where the debtor is the surety's client, in the matter of the attorney signing a bond for instance, but these rules are made rather for the purpose of justifying the public officer in the rejection of such a surety, rather than to make the contract of such a surety invalid once it has been entered into, and once such a surety has been accepted as such, he is usually bound on his contract notwithstanding the law's prohibition against his acceptance under the circumstances of the particular case.
