  Client->>Neuron: Legal/CreateContract
  Neuron-->>Client: contractId
  Client->>Neuron: Legal/SendProposal
  Neuron-->>Client: proposalId
  Client->>Neuron: Legal/SignContract
  Neuron-->>Client: signed contract
```

## Steps

1. Create a contract with `Legal/CreateContract`.
2. Send a proposal to counterparties with `Legal/SendProposal`.
3. Sign the contract using `Legal/SignContract`.
4. Retrieve signed or created contracts with `Legal/GetSignedContracts` and `Legal/GetCreatedContracts`.
