A son in the mother's womb is part of the mother's vitals.

Explanation

(English-origin maxim.) An unborn child is considered part of the mother — this maxim bears on inheritance rights and the legal status of the unborn.

Where this applies

• An inheritance question turns on whether a child conceived but not yet born can take.
• A gift is made to 'the children,' and whether an unborn child is included must be decided.
