§ 117. Certain contracts and expenditures prohibited. Except as
authorized by law, no officer, board, department or commission shall
during any fiscal year expend or contract to be expended any money or
incur any liability or enter into any contract which by its terms
involves the expenditure of money for any purpose, unless provision
therefor shall have been made in the annual budget, and in no case in
excess of the amount appropriated for such year, except pursuant to
section one hundred twelve of this chapter and further excepting such
leases and contracts as may have been entered into by the town for a
term exceeding one year in accordance with the provisions of this
chapter or any other law applicable to such town. Nothing in this
section shall be construed to prevent the allowance of any claim by the
town board for any lawful town purpose in excess of the amount
appropriated for such year for such purposes, where the said town board
has by resolution transferred sufficient funds to said budgetary fund in
accordance with section one hundred twelve of this chapter, and nothing
in this act shall be construed to prevent the town supervisor or the
town comptroller from paying amounts in excess of the amounts
appropriated for such year in the annual budget where such transfer has
been made, nor shall anything in this act be construed to require a town
which has entered into a lease or contract for a term exceeding one year
to pay during the current year any amounts larger than those which
become due and owing during that year under the terms of such lease or
contract. Any contract, verbal or written, made in violation of this
section, shall be null and void as to the town and no money belonging to
the town shall be paid thereon. Nothing herein contained shall be
construed to prohibit the town board from making contracts for periods
exceeding one year for the purposes of improvement districts whenever
authorized by law.
