Spinda relationship is banned under hma
"Sapinda relationship" with reference to any person extends as far as the third generation (inclusive) in the line of ascent through the mother, and the fifth (inclusive) in the line of ascent through the father, the line being traced upwards in each case from the person concerned, who is to be counted as the first generation.
Two persons are said to be "sapindas" of each other if one is a lineal ascendant of the other within the limits of "sapinda" relationship, or if they have a common lineal ascendant who is within the limits of "sapinda" relationship with reference to each of them.
Example
For example, if the bride is the offspring of any person within five generations (inclusive) on the groom's father's side and three generations (inclusive) on the groom's mother's side, or vice versa, they will be referred to as "sapindas" of each other. In these cases, the Hindu Marriage Act of 1955 bars marriage between two Hindus.
