I dissent and vote- to affirm. The plaintiff here sues for additional alimony pursuant to a separation agreement. The agreement is clear that such additional payments are to be based upon an increase in the defendant’s *327net income. The reference to item 3 on page 3 of the husband’s Federal tax return for the year 1952 indicates that the net income there referred to was the sum remaining after all permissible deductions were taken. Obviously, alimony was not there listed because it was not then being paid. Since 1942, alimony has been an allowable deduction. The parties must be taken to have entered into the agreement with knowledge and in contemplation of existing law. If it were the intention of the parties to exclude an item properly allowable as a deduction from the computation of net income, it should have been expressly set forth. The term “ net income ”, in my view, is to be construed in its ordinary sense, and the intent of the parties as expressed in the language of the contract should be given effect. It is not for the court by construction to rewrite the agreement of the parties.
