In the Bridgerton books and the related discussions about the story, Sophie is connected to Lord (Earl) Penwood’s will, but she is not treated like a legitimate, openly acknowledged heir.

Was Sophie in Lord Penwood’s will?

  • In the book backstory, Lord Penwood makes financial provisions that indirectly “take care” of Sophie after his death, including arrangements that result in money being available to those who keep her in the household.
  • Readers discuss that the late earl’s will provides an allowance tied to Sophie’s presence, and that she is meant to have a dowry funded via Lady Penwood because of what the earl stipulated.
  • However, Sophie herself is not treated as a recognized, legitimate daughter in the will; she receives no open inheritance of title or estate and ends up effectively as an unpaid or underpaid maid under Araminta’s power.

How the show and fandom frame it

  • In the Netflix series context, Sophie is the illegitimate child of Lord Penwood, raised publicly as his “ward,” which lets him support her without admitting she is his daughter, and the question of what (if anything) she is due from his will is left murky and dramatic.
  • Articles and forum threads note that “questions around Lord Penwood’s will” and Sophie’s possible inheritance are intentionally teased, implying there may be more to discover about what he left for her—materially or symbolically.

Short version: yes, there are provisions tied to Sophie in Lord Penwood’s will (especially in the book canon), but she is not written in as a full, acknowledged heir to his title or estate; instead, her support and potential dowry are hidden and conditional, which is why she ends up in such a precarious position after his death.
