How to file a creditor claim in insolvency proceedings

When this applies

This guide applies when a debtor is no longer merely late with payment but is of­fi­cial­ly subject to in­sol­ven­cy pro­ceed­ings. A sup­pli­er, land­lord, or con­trac­tor in Lviv may have signed state­ments and an ac­knowl­edged debt, but that alone is not enough to par­tic­i­pate in the pro­ceed­ings: the claim must be filed in the case.

Start by iden­ti­fy­ing the debtor. Company names can be similar, so check the EDRPOU code, case number, and court. If the cred­i­tor op­er­ates in Lviv Oblast, that does not mean the ap­pli­ca­tion will be heard by the Com­mer­cial Court of Lviv Oblast: the proper court is already de­ter­mined by the open case and named in the notice.

Which deadline or procedure applies

For an in­sol­ven­cy claim that arose before pro­ceed­ings opened, Article 45 of the Bank­rupt­cy Code sets a 30-day period from the date the notice is of­fi­cial­ly pub­lished. The pub­li­ca­tion date itself is day 1. If the notice ap­peared on 28 October 2025, cal­en­dar day 30 falls on 26 No­vem­ber 2025.

Check the date with the cred­i­tor claim dead­line cal­cu­la­tor for in­sol­ven­cy pro­ceed­ings. It will not cal­cu­late the period if you mark the claim as current, fully secured, special, or un­cer­tain. A Sat­ur­day or Sunday rollover is shown as a basic as­sump­tion; before filing, check the court’s actual sched­ule, wartime holiday rules, and the op­er­a­tion of the elec­tron­ic system.

If the 30 days have already passed, file without delay. The claim is not au­to­mat­i­cal­ly ex­tin­guished solely because the dead­line was missed, but the cred­i­tor will not have a de­ci­sive vote, and earlier pro­ce­dur­al actions and court de­ci­sions will bind them. The Code does not provide for au­to­mat­ic restora­tion of this period.

Steps to take

Save the of­fi­cial notice and record when you checked it. Build a time­line for the con­tract: when goods were de­liv­ered or ser­vices pro­vid­ed, when payment fell due, which amounts arose before pro­ceed­ings opened, and which arose af­ter­ward. De­scribe any pledge, mort­gage, or other se­cu­ri­ty sep­a­rate­ly.

Prepare a package of ev­i­dence, not just a total from ac­count­ing soft­ware. Each com­po­nent needs a legal basis, cal­cu­la­tion, and source doc­u­ments. Ma­te­ri­als col­lect­ed for a debt re­cov­ery claim may provide a start­ing point, but adapt the ap­pli­ca­tion to the re­quire­ments of the in­sol­ven­cy pro­ce­dure.

State the case and party details, the amount, and the cir­cum­stances giving rise to the claim. Check the current court fee on the filing date; do not copy an amount from an old sample. Send copies to the debtor and prop­er­ty ad­min­is­tra­tor, keep the re­ceipts and mailing in­ven­to­ries, and file the ap­pli­ca­tion with the court named in the notice.

What to check before filing

Cor­rect­ly sep­a­rat­ing the debt is es­sen­tial. A de­liv­ery made before the case opened and ser­vices pro­vid­ed after that date may create claims subject to dif­fer­ent rules. A mort­gage or pledge also changes the cred­i­tor’s status and may cover only part of the amount claimed.

Before sending, check the sig­na­to­ry’s au­thor­i­ty, qual­i­fied elec­tron­ic sig­na­ture, file names, scan leg­i­bil­i­ty, at­tach­ment num­ber­ing, and proof that copies were sent. Filing early leaves time to respond if the court finds a formal defect.

When to consult a lawyer

Legal help is useful if the claim com­bines dif­fer­ent types of debt, is secured, de­nom­i­nat­ed in foreign cur­ren­cy, con­firmed by another court’s de­ci­sion, or dis­cov­ered after the 30 days have passed. A cal­en­dar cal­cu­la­tion is not enough: you need to de­ter­mine the legal status of each amount, the con­se­quences of missing the dead­line, pri­or­i­ty, and ev­i­dence.

For busi­ness­es in Lviv and the region, a lawyer can review con­tracts and ac­count­ing records, prepare the cal­cu­la­tion and ap­pli­ca­tion for the court han­dling the case, and rep­re­sent the cred­i­tor even when the in­sol­ven­cy pro­ceed­ings are taking place in another region.
