This is an overview of transactions that involve more than one signer. Below are brief descriptions of each.
Co-located signing: Signers are in the same room and join the same notary meeting together on one device (computer or mobile). For users sending a transaction on behalf of their organization, up to 2 signers are allowed for this type of transaction.
Concurrent signing: Signers are in different locations and simultaneously join the same notary meeting from separate devices.
Split Signing: Signers are in different locations and meet with a notary separately.
For all multiple-signer transactions, each signer must separately complete their own identity verification.
Each type of multi-signer transaction has different requirements. This table provides an overview of each main type of transaction requiring multiple signers.
| Type | Physical location | Device | Notary meeting |
| Co-located | Together | Same device | Same meeting |
| Concurrent | Separate | Different device | Same meeting |
| Split signing | Separate | Different device | Separate meeting |

ℹ️ A total of ten (10) devices can connect to a meeting. One must be a notary and one must be a signer; the rest can be any combination of participants (signers, real estate contacts, etc.), with a maximum of 2 witnesses.
Who pays for a transaction with multiple signers
For transactions for multiple signers, we ask the last signer to pay for all required fees so that the documents can be available to all parties as soon as they're finished.
For transactions that involve one or more notary meetings, the first signer to join the final meeting is asked to pay for the transaction.
Payment is required at the end of the transaction.
If an organization sent you the transaction, they may cover the cost. Read more about How much does notarization cost on the Proof platform?
