Which character became House’s wife in House M.D.?

Dominika Petrova became House’s wife in House M.D. House marries Dominika during the show’s eighth season so she can obtain legal residency in the United States.

Dominika is a Ukrainian woman who initially meets House through a matchmaking arrangement. Their relationship develops through a mixture of practical motives, mistrust, affection, and House’s tendency to manipulate situations. The marriage is legally real, although House initially treats it as a strategic arrangement rather than a conventional romance.

Dominika later discovers that House had concealed important information about the status of her immigration application. Their relationship ends after she learns that her green card has been approved and leaves him. The storyline reflects House’s recurring difficulty with honesty and emotional commitment.

Dominika is played by Karolina Wydra. She is not the same character as Lisa Cuddy, House’s former employer and romantic partner, or Stacy Warner, his earlier relationship. Those distinctions are common sources of confusion when identifying House’s relationships.
