# <init>

`Client(stx: SignedTransaction, skipVerification: Boolean = false)`
`Client(stx: SignedTransaction, progressTracker: ProgressTracker)` `Client(stx: SignedTransaction, progressTracker: ProgressTracker, skipVerification: Boolean = false)`

A flow to be used by a party for obtaining signature(s) from a NotaryService ascertaining the transaction time-window is correct and none of its inputs have been used in another completed transaction.

In case of a single-node or Raft notary, the flow will return a single signature. For the BFT notary multiple signatures will be returned – one from each replica that accepted the input state commit.

The transaction to be notarised, stx, should be fully verified before calling this flow.

### Exceptions

`NotaryException` - in case the any of the inputs to the transaction have been consumed by another transaction or the time-window is invalid or the parameters used for this transaction are no longer in force in the network.
