Serov and Somov were co-owners (in equal shares) of a residential building. After a fire broke out due to Serov’s fault and the house had to be repaired, the relationship between them deteriorated so much that Serov decided to sell part of his apartment house and move to another place. Through an intermediary, he verbally informed Somov of his intention, indicating the price for which he would like to sell his part of the house. Reactions from Somov was not followed.
After some time, Andreev appeared on a part of the house where Serov had previously lived, and declared that he had entered into a donation agreement with Serov, according to which the latter donated part of the house to Andreyev. Somov went to court with a claim to transfer part of his house to him, since, in his opinion, he, as a co-owner, had a preferential right to receive it.
