OPINION
ALAN M. AHART, Bankruptcy Judge.

FACTS AND PROCEDURAL HISTORY
Debtor, an attorney at law, filed a petition under Chapter 13 of the Bankruptcy Code on September 6, 1985. Debtor’s Chapter 13 Statement listed $5,590 in monthly take-home pay and $4,590 in monthly expenses. Debtor proposed a plan that was subsequently amended. The amended plan provided, inter alia, that the debtor would pay to the trustee future earnings of $1,000 per month for 36 months and that unsecured creditors holding claims totalling $91,224 would receive $33,120.30, or a dividend of about 36%. No one objected to the amended plan, (hereinafter the “plan”) and an order confirming the plan was entered on December 16, 1985. The order became final 10 days later.
The debtor paid a total of $39,660.00 to the trustee. Of this, $7,760 was sent to the trustee on March 22, 1988, in the form of seven (7) checks for $1,100 each and one check for $60.00 for additional attorney’s fees. The March 22, 1988 checks completed the debtor’s payments under the plan about seven months earlier than required.
On March 29, 1988, the trustee filed and served an objection to the debtor’s discharge. • This objection asserted that the debtor failed to comply with 11 U.S.C. Section 1325 (b)(1)(B) requiring a Chapter 13 debtor to devote all of his projected disposable income to be received during the three years following the due date of the first plan payment to make payments under the plan. The objection alleged that the trustee had received all payments required by the plan due through November 1988, including $7,760 on March 23, 1988, that the debtor’s actual monthly take home pay in 1985 and 1986 was $6,756.09 and $5,919.07, respectively, that the debtor had not furnished proof of income for 1987, and that the confirmed plan paid unsecured creditors 40% of their claims. The trustee also contended that, because the debtor’s legal obligation to make payments to his ex-spouse ended in January 1986, after that date the debtor had additional income available to pay unsecured creditors.
Notwithstanding the trustee’s objection, an order granting the debtor a discharge was signed on April 1, 1988. Consequently, the trustee also filed a motion to vacate the discharge order.
The debtor filed a response to the trustee’s objection, contending that all payments under the plan had been made and that the order confirming the plan was final and non-appealable. The debtor also argued that sections 1325 and 1329 of Title 11 of the United- States Code do not apply to the case at bar because section 1325 only applies before a plan is confirmed and section 1329(a) does not permit modification after all payments under a plan have been made.

ANALYSIS
A. The “Disposable Income” Test of Section 1325(b) Does Not Apply at the Time of Discharge
11 U.S.C. section 1325(b)(1)(B) states, in pertinent part:
