Potential claimants will need to prove that they (1) own property/investment that (2) has suffered damage (3) due to russia's aggression against Ukraine. To this end, it is necessary to collect:

(1) Evidence regarding the claimant's identity and property/investment (with a detailed description of its qualitative and quantitative characteristics): 

• collect documents confirming the identity and origin of the company or individual; 
• collect documents confirming the ownership or use of the damaged property; other documents confirming the characteristics, the market value before the full-scale invasion, and other specifics of the investment. 

(2) Evidence of damage caused by russia's war against Ukraine. 

• If there has been physical damage to property, it is worth collecting any possible photo and video evidence, witness statements, and materials from public sources. It is also necessary to prove that the damage was caused as a result of the war, e.g. that there were hostilities or rocket attacks in a certain area at the time. 
• If the property itself was not damaged, but the losses were caused by the inability to do business normally for a certain period of time, it is necessary to prove that the business is not operating and explain why, e.g. provide information that a certain place was regularly shelled or that the property could not be used for a certain period of time due to temporary occupation. 
• The cost of restoring the property, lost rent, etc. may also be included in the damages. 
• The best evidence to prove the amount of damage is an expert opinion. 

1. Expertise, reputation, and experience in already resolved cases where claimants were awarded large amounts of compensation (Yukos case).
2. Opportunity to receive compensation for direct and indirect losses.
3. Existing practice of international arbitration in "Crimean cases".
4. Changes in the arbitration approaches in line with the development of public international law – the recent ECtHR judgment on jurisdiction in the Donbas case may open the door to claims by investors for loss of investments in the territories of Donetsk and Luhansk regions occupied in 2014.
5. Respect to, recognition and enforcement of arbitral awards in any country of the world.
6. Flexible approach to the statute of limitations (claims can be filed for damages that have been caused since 2014).
7. Interest on the amounts awarded, which is accrued during the arbitration proceedings and until the arbitral award is actually enforced.
