English to Russian Law/Patents Law (general) обязанности доверительного собственника

This rule is a strict rule which developed from the rule in Keech v Sandfordfi, in which case a trustee sought to renew a lease which previously he had held on trust for an infant beneficiary. The beneficiary, being an infant, was not able to take out the new lease in his own name and therefore the trustee took out the lease in his own name instead.
