Paid contracts
Civil relations are also subdivided depending on whether the party that has fulfilled the terms of the agreement will receive a counter-grant (payment) or not. A contract for the provision of services does not necessarily imply equivalence. A counter offer may be expressed either in the form of a monetary amount (counter price) or a product / work. In these cases, under the contract for the provision of services, the contractor is obliged to fulfill the conditions. In this case, the second party must provide a fee. If one participant fulfills the conditions without receiving anything in return, the contract is called gratuitous.
The legislative framework
Within the framework of certain civil law relations, certain rules apply. Some rules of the Civil Code contain direct indications of onerous contracts. For example, in Art. 685, paragraph 3, it is provided that the agreement for the sub-lease of residential premises is concluded with a counter provision. In Art. 572 there is an indication of gratuitous gift contracts, and in Art. 689 - use (loans). For some agreements, a counterclaim is not presumed. So, for example, in Art. 1016, paragraph 1, there is an indication that remuneration to managers is paid if it is provided for in the trust deed. 
Guarantee
The conditions in art. 972 Civil Code.In accordance with it, reimbursable assignment contracts may be concluded, as well as without counter provision. The former takes place when the agreement concerns the implementation of entrepreneurial activities by the participants. In other situations, according to the rule of Art. 972 Civil Code, assignment contracts are assumed to be free. In these cases, the principal can pay a fee. However, this is permitted if provided for in legislative acts or in an agreement.
Loan
As a general rule, upon receipt of such funds onerous contracts are concluded. But in some cases, agreements can be interest-free. For example, if:
- It consists of an amount not exceeding 50 times the minimum wage and does not apply to at least one participant in entrepreneurial activity.
- By agreement, the borrower shall transfer things determined by patrimonial characteristics, but not cash.
Upon receipt of loans, onerous contracts are always concluded. In this case, a prerequisite is the payment of interest on the transferred amount. 
Storage
In this case, a contract of onerous services with an individual may also be concluded. Storage is provided for in Art. 886 Civil Code. The article does not directly indicate that it should be carried out with the obligatory counter provision. The transfer of something in return may be provided for by agreement (under Article 891) or legislation (for certain types). For example, in Art. 907, the contract for the provision of services for warehouse storage is expressly provided for, and in Art. 920 - in a pawnshop. This category also includes agreements in which one of the parties is an organization that carries out this activity professionally.
Paid agreement: sample
Like any similar document, this agreement must contain the required details. These include, in particular:
- The name of the contract.
- Place and date of conclusion.
- Details of the parties.
The agreement shall indicate the subject of the contract and information about it. For example, if this is a storage agreement, you must specify the name of the property, its quantity, units, total cost. The agreement establishes the conditions for the transfer of the facility, the provision of services, the delivery of goods, and so on, as well as the time frame by which this must be fulfilled. The parties also establish the payment procedure. The contract also defines the obligations and rights of the parties, responsibility for violation of the conditions. The agreement may provide for additional clauses. Details of the parties are usually given at the end of the document. Under them, the parties affix their signatures (and stamps if this is a legal entity).
