OPINION
HOLMAN, Justice.This is an appeal from an order revoking appellant’s probation of his conviction of burglary of a building. V.A.C.C.P. art. 42.-12.
We reverse and remand.
Appellant was convicted of burglary on April 21,1978. Punishment was assessed at not less than two years nor more than seven years, probated.
The State subsequently moved to revoke probation, alleging that the appellant violated the terms and conditions of his probation by failing to pay his probation fees of $10.00 per month, and also passing a check upon which he forged his mother’s signature. To each allegation, appellant pled “untrue”.
At the revocation hearing January 16, 1981, the court found appellant had committed both of the alleged violations and signed an order revoking probation and assessing punishment at seven years.
Appellant complains that there is (1) no evidence that his failure to pay his probation fees was intentional and (2) insufficient evidence to sustain the forgery allegation.
The evidence is that the appellant paid each monthly probation fee except those due in September and October, 1980. He was employed and had the ability to pay the fees at all times material to the case.
Appellant testified that he believed he had paid the September and October fees, and that his failure to pay was not intentional. The record contains no evidence that he intentionally failed to pay.
The general rule is that if probation is to be revoked on the ground that the probationer failed to pay supervision fees, the State must prove that (a) the probationer had the ability to pay and (b) his failure was intentional. Curtis v. State, 548 S.W.2d 57 (Tex. Cr. App. 1977).
The Legislature has modified the rule to the extent that in cases where non-payment of fees is the only ground upon which revocation is sought, the probationer’s inability to pay is an affirmative defense which he must raise and prove by a preponderance of the evidence. V.A.C.C.P. art. 42.12, sec. 8(c). In those cases, if the probationer fails *129to raise the affirmative defense, then the State is no longer required to prove that the probationer had the ability to pay and intentionally failed. Jones v. State, 589 S.W.2d 419 (Tex. Cr. App. 1979).
In the case at bar, revocation was sought on two grounds, and we hold that the State therefore was required to prove that the appellant had the ability to pay and that he intentionally failed to pay. Curtis, supra.
The State proved ability, but did not prove intent, and we sustain appellant’s first ground of error.
Because probation may be revoked upon proof of only one violation of the conditions of probation, appellant’s second ground of error is material.
To prove that the appellant violated the conditions by forging a check on his mother’s bank account, signing her name as drawer, the State’s burden was to establish that the appellant wrote the check without his mother’s authorization and with the intent to defraud or harm her. V.T.C.A. Penal Code sec. 32.21.
Appellant admits that he wrote the $30.00 check on his mother’s account and cashed it, on October 13, 1980. The evidence is that he had written and cashed checks on her account on two previous occasions, to which his mother had not objected, and though she learned her son had used her account in that manner, she never instructed him to refrain from doing it again.
Appellant testified that he had repaid his mother for the two prior checks and was willing to repay the October 13 check.
We hold that the evidence is insufficient to prove that the appellant wrote and cashed the October 13 check with the intent to defraud or harm his mother.
The second ground of error is sustained.
Judgment is reversed, and the cause is remanded.
