Hello,

Will somebody kindly provide an advice about the following situation:

1. Assume you completed a project for, say, $1000 for a client and he should submit the payment at the end of the project.

2. But for some reasons he does not do pay for a few months.

3. A few months later, however, you find a method to convince him to pay.

Now the question. Do you theoretically have the right to require not $1000 (the initial amount) but more? A few percents per month, perhaps?

Yes, I understand that 99% of all flashers would not try to require that additional amount. But my question is whether there exist theoretical/legal/official reasons to do that.

Thank you in advance for your information,

Vahagn
