How to Check Mutation in Assam — Complete Guide 2026
Mutation Assam, locally called namjari, is the quasi-judicial process that transfers the seller's name out and your name into the Jamabandi after a sale, gift, or inheritance. You must verify the mutation at both the Circle Office and the Dharitree portal. This guide covers how, fees, time, and red flags.
What is Mutation in Assam?
Definition
Mutation in Assam is the quasi-judicial process of updating the new owner's name in the Jamabandi (Record of Rights) after a transfer of title. The process runs under the Assam Land and Revenue Regulation, 1886 read with the Assam Land Records Manual, 1906.
Registration of your sale deed at the Sub-Registrar is not the end of the job. It just records that a sale happened. Mutation is what actually shifts the land into your name in revenue records. Without it, you can't pay khajana in your name, can't apply for a home loan, and can't sell or gift the plot later. The seller's name keeps appearing on Dharitree. That's a problem you don't want six months from now.
Assam runs mutation through three doors: mutation after deed registration (post-sale), mutation by right of inheritance (post-death), and office mutation (both urban and rural). The Sewa Setu portal lists each as a separate service. Mission Basundhara 3.0 has now added auto-mutation, which auto-fetches the deed from the Sub-Registrar and pushes it to the Circle Officer. You still need to track the case yourself.
How to Get Mutation in Assam: Step-by-Step
You can file a mutation online through Sewa Setu, or walk into the Circle Office with a paper application. Either way, keep the registered deed, khajana receipt, ID proof, and ceiling affidavit ready.
