Enables the user to create a mutation and transfer the ownership to the new owner.
Workflow config:
In Addition to property information and the extra owner information being added, some other information is required for workflow
The Creation Reason in the property should be sent as MUTATION for the request to be considered as a mutation request.
Along with the workflow name for mutation, a few extra details have to be provided in the additional details field of the property. Also either a new owner has to be added or an existing one has to be set to inactive for a valid mutation request.
The business workflow config follows the structure given for property workflow with respective name changes.
Workflow sample config for Mutation.
The property services will make a call to the mutation calculator at the required interval during the mutation flow.
The mutation service belongs to the property service itself and provides the same ease of access for the functionality.
Pick a property id that is already created in the system.
call the property/update API by changing the owner information or adding new owner information.
workflow information must be added mandatorily before submitting the request.
The calculation logic for mutation fee depends on the usage type of property (RESIDENTIAL, NON-RESIDENTIAL, etc ) and the current market value of the property.
If the current market value (CMV) of the property comes in between the minimum and maximum market value range of billing slab and the usage type of property match with the usage type for that billing slab then the mutation fees for that property is the amount mentioned in that particular billing slab.
Further, there are two calculation types which are FLAT and RATE which have to set by state/ULB for their billing slab for property mutation. If the calculation type is set as FLAT then mutation fee is the fixed amount mentioned in the billing slab which is used for the property.
If the calculation type is set as RATE the Mutation fee is X% of the current market value, where X is the percentage rate mentioned in the billing slab which is used for the property.
Other factors influencing calculation can be :
Ownership type
Property type
Locality
When the property is registered for mutation/transfer of ownership and all the document is submitted, then the mutation fees have to pay within a specified period of time of property mutation registration date. If a person fails to pay the amount of the fee before the deadline date, then some penalty charges have to pay. The penalty charge is Y% of the tax amount. The penalty percentage is set by the state/ULB. If a person pays the amount of the fees within the specified month of the property mutation registration date, then a certain amount is rebated from the tax amount. The rebate charge is Z% of the tax amount. The rebate percentage is set by state/ULB.
Note: For mutation fees calculation, document date value (means the date at which property is registered for mutation), market value of property, usage type value of the property is essential.
