which form to transfer from tenants in common?

Presently our property is registered as ownership by my husband and myself as tenants in common. We would like to transfer it to joint ownership - which forms do we need to do that? Thank you

Jennifer - I assume you mean that you are registered as joint owners and there is a form A restriction (often applied for when joint owners server their joint tenancy/change to tenants in common) on the register
If so then there's no transfer to complete but you can apply to cancel the form A restriction by changing from TIC to JTs
