What is a title chain when you’re buying a property

Let me narrate this as a story.

There is a piece of land (say Site no 80 in Survey No 5) that you i.e Suhas have finally shortlisted to buy, and you need to know the background information how the land has passed from one to another.

1. Suppose the land (Sy No 5) was originally a agricultural land in 1970 under the ownership  of say Mr. Shyam( mentioned in RTC-Record of Rights, Tenancy and Crops. In Karnataka, it is one of the most important land-revenue records for agricultural properties).
2. Later Shyam who has 2 daughters and 2 sons writes a will which mentions that he has distributed his wealth among all his four children’s equally he would also mention that all three children has no obligation for the piece of land Survey no 5  that he has given to his son Murali via a gift deed  via DOC NO  1234-1972-73 Registered at Anekal SUB REGISTER OFFICE (SRO). So this will be the mother deed or origin deed from where your land was born on land records.
3. Now Murali now wants to sell his survey no 5 to Mr.Ram ,Now Mr.Ram has to check the previous gift deed DOC NO  1234-1972-73 in detail he has to makes sure that all children’s (inclusive for minor Grandchildren’s) of Shyam had given consent for the property transfer to Murali. Now all the piece of Survey no 5 get registered in the name of Mr.Ram via doc no ANK-04567-1980-81 registered at Anekal SRO in 1980-81.
4. Mr.Ram being a RE developer now wants to develop the agricultural land to a residential layout and approaches Deputy Commissioner Office of Anekal to apply for conversion and gets permission via conversion order ANK7890-2000-01. Conversion order indicates the Survey no 5 Acreage area clearly mentioning the land can now be used for residential purposes.
5. Survey no 5 is now broken down into various no of sites say from site 1 to site 100 and Ram applies for individual Khata for each site in Anekal SRO.After getting permission he then sells these sites to another builder say XYZ SPACES represented by director Laxman via a absolute sale deed numbering ANK1122-2010-11.
6. During the registration few minor and major errors were committed in the registered sale deed ANK1122-2010-11, to get these errors rectified Laxman then calls Ram for executing the rectification deed in ANEKAL SRO. Thus making the registered sale deed ANK1122-2010-11 error free.
7. Now Laxman of XYZ SPACES wants to improve the landscaping , infrastructure and marketing of  these sites, He approaches  NMDC BANK. for loan and gets a loan sanction of 25 Cr. Laxman director of XYZ SPACES now executes a Mortgage deed numbering ANK4455-2022-23 with NMDC banking head mentioning all these sites are mortgaged for NMDC bank till the loan is completely paid off.

Suhas now approaches XYZ SPACES for buying the site no 80 .

Suhas has to make sure that he Laxman has given documents relating to events from 1 to 7. The chronological order of these events make the Title chain for the site no 80.

After due verification Suhas now executes a Absolute sale deed with Laxman of XYZ SPACES in Anekal via doc no ANK-8899-2024-25. This sale deed of Suhas should contain exact names, doc no, dates of the events 1 to 7.

This ultimately makes Suhas the registered owner of the site no 80.
