Dear client,  

If your wife adds her daughter's name as a joint owner on the RTC, then it would mean that her daughter would have an equal right over the agricultural land, including the house that you have built. This could potentially cause issues in the future, as you may have to deal with the daughter's claim on the property.
To avoid this situation, you could try to discuss the matter with your wife and explain your concerns. You could request her to keep the RTC in her name alone, or you could work out an agreement where your ownership rights over the house are legally recognized, even if your name is not on the RTC.

You could also consider getting legal advice from a lawyer to understand your options and to draft a legally binding agreement that recognizes your ownership rights over the house.

E-Swathu is a digital record of property details maintained by the Government of Karnataka. Even though your name is not on the RTC, it is possible to add your name to the E-Swathu record, provided you have proof of ownership such as sale deed or any other relevant document.
You could approach the revenue department in your area and request them to add your name to the E-Swathu record. However, it is important to note that adding your name to E-Swathu does not give you ownership rights over the agricultural land or the house. It is only a record of property details maintained by the government.

Therefore, it is important to work out a legally binding agreement with your wife to ensure that your ownership rights over the house are protected, even if your name is not on the RTC or E-Swathu record.

- Since, the property is in name of your wife, then you cannot include your name in the RTC as joint owner. 

- Further, if she include daughters name , then she will become 50% share holder of this property and she cannot claim the entire property after demise of your wife. 

- Further, after the demise of wife, you will have right over 25% share in the property ., and rest will go to daughter. 

- Further, if  you have funded for purchasing and constructed the house , then you can be declared the owner of the property after filing a declaration suit before the court. 

1. Your concern is valid. If your wife's daughter is added as a joint owner, then legally, she will also become the owner of the house. However, you can take steps to protect your ownership rights. You can execute a registered gift deed or sale deed with your wife, where she can transfer a portion of ownership in the house to you, thereby making you a co-owner. Alternatively, you can also enter into a written agreement with your wife and her daughter, wherein all parties agree to give up their right to claim any ownership rights in the house, and you can be recognized as the sole owner.

2. Your name can be included in the e-Swathu portal, even if it is not listed in the RTC, provided you have the required legal documents such as the sale or gift deed, which proves your ownership in the property. You can approach the concerned authorities to update the details in the e-Swathu portal.
