Can I use funds in my Thai bank account for a stay extension application after they have been untouched for a year?

If I apply for a 1 year stay extension based on marriage using 400k transferred to a Thai Bank account to meet the financial requirements then leave those funds in the account untouched can I use those funds to apply for a stay extension next year on the basis that they were transferred from overseas and have been in the account for more than 2 months? A friend told me that he has been doing this for years but I wanted to confirm that it is an acceptable practice.
