You can continue to edit a provisionally filed (line in a) claim. The curator will be notified if you adjust the provisionally submitted amount after the curator has already edited this line. Once you have definitively budgeted the amount, please untick the "provisional" box.
Please note that the curator will make a final decision on your claim in the 3rd Review of Insolvency of your claim. Adjustments after the 3rd Review of Insolvency are not possible.
