The contraction for “should have” is “should’ve.”
The contraction for “should have” is “should’ve.”
Because the “ ‘ve” sounds like “of,” a common mistake is to use “of” after “should.” In this situation, “should” is followed by the present perfect (“have” plus the past participle).
“Should of” is acceptable in informal dialogue, but not in the narrative.
In a negative sentence, this contraction follows the “n’t” with its own apostrophe, making a double contraction, “shouldn’t’ve.”
Wictionary has an interesting list of double contractions, including some in which the apostrophe begins the word.
