The court notice is with regard to the execution of the due amount from you that you had promised to pay for the education of your daughter.
If you want to challenge it you first will have to check what actual terms and conditions were with regard to payment of money for education of the daughter. If you never mentioned limit to which you will be paying for the education, the enhancement of fee and other expenses for the education of daughter will be said to cover in those terms and conditions.
As you state your ex-wife spend Rs25,000/- but is demanding Rs79,000/- as recovery of due in this regard, in such case you should take Rs25,000/- with you on the date of appearance with you in the form of Bank Draft and deposit in the execution court. Along with this you can object for the demand of Rs54, 000/- more than from the due amount from you. The onus to prove that the amount of Rs54,000/- was also spent by your ex-wife on the education of the daughter will be for her to prove with documentary evidence like receipt of the payment for the education of daughter, if she fails to prove it her demand of Rs54,000/- more will be rejected by the Family Court.
