Is there a time limit for requesting amendment in EU funded grant projects?  

As stated in the General Conditions of the contract, the beneficiary should submit the amendment request in written format as soon as the need for amendment is identified and prior to any intended changes taking effect for unilateral amendments. For amendments by addendum, the beneficiary should inform the Contracting Authority (is EUD under the direct management modality) 30 days before the date on which the amendment should enter into force. Note that the contracts cannot be amended after the end of the implementation period.
