On 29 April 2026, the Register of Damage for Ukraine (RD4U) opened new categories of claims for businesses regarding damage caused by the armed aggression of the Russian Federation. Below is a guide on who can file a claim, what documents are required, and how to proceed.
On 29 April 2026, the Register of Damage for Ukraine (RD4U) (the “Register“), established at the initiative of Ukraine, the European Union and 42 states, to facilitate compensation claims for damage caused by the armed aggression of the Russian Federation, announced the launch of new claim categories for businesses and the State of Ukraine.
Businesses are now eligible to officially submit claims for damage caused by armed aggression.
The newly introduced business claim categories include:
- C1.1 – Damage to or destruction of critical infrastructure;
- C1.2 – Damage to or destruction of non-critical infrastructure;
- C3.1 – Damage, destruction, or loss of assets.
These categories are determined based on the type of property damaged or destroyed.
When can a claim be submitted?
The Register allows legal entities, regardless of ownership structure or institutional affiliation, to submit claims for material losses caused by the armed aggression starting from 24 February 2022.
The Register does not provide an exhaustive list of events giving rise to compensation claims. Eligible events may include direct military attacks, acts of sabotage, occupation, cyberattacks, supply chain disruptions, logistics interruptions, and similar consequences of the aggression.
Claims may be submitted in relation to:
- damage to, destruction of, or loss of property and/or related loss of profit;
- complete loss of business resulting from the destruction of property;
- any other direct expenses arising from the destruction of property.
The affected property must be located within Ukraine’s internationally recognised territory.
Claims may cover not only damage or destruction itself but also expenses already incurred for restoration or recovery of the property.
What documents should be prepared?
To successfully submit a compensation claim, businesses are advised to secure documentary evidence confirming the fact of the damage; the amount of losses incurred; and ownership or lawful possession of the damaged or destroyed property.
Both official (court decisions; law enforcement resolutions; reports issued by the State Emergency Service of Ukraine etc.) and unofficial evidence (media publications; photographs and videos; witness statements; and other supporting materials) may be used to substantiate damage caused by the armed aggression.
We recommend collecting as much supporting evidence as possible and not limiting submissions to formal official documents only.
The Register also does not establish a strict list of evidence regarding the amount claimed, provided the claim is properly substantiated. Supporting documents may include invoices, sale and purchase agreements, financial statements, contracts, and similar records.
At the same time, obtaining an independent expert assessment of losses is advisable, as it may help quantify both direct property damage and lost profits.
It should also be considered that only duly substantiated claims will be included in the Register, while the burden of proof and associated risks remain with the claimant legal entity.
How to submit a claim?
Claims are submitted electronically through the Ukraine’s state digital services portal, Diia, by logging in to user account and completing the relevant application form.
A claim may be submitted on behalf of a legal entity either by its director or by an authorised representative – any individual with full legal capacity. For this purpose, the Diia portal provides the “Digital Authorisation” service.
What happens next?
Following submission, the claim is reviewed by the Register’s Secretariat for formal compliance and then referred to the Register Board, which determines whether the claim is admissible for inclusion in the Register.
Although no specific review deadlines have been established, the Register Board holds in-person meetings at least once per quarter to consider submitted claims and decide whether to register or reject them.
Applicants are notified of the decision through the Diia web portal.
The Register and its governing bodies are not authorised to determine the amount of compensation or make compensation payments. These functions are expected to be assigned to separate institutions to be established in the future.
The opening of the Register to businesses is undoubtedly an important and significant step toward compensation for losses caused by the armed aggression. It demonstrates that an effective compensation mechanism is becoming increasingly tangible.
