David is currently planning to marry close friend Alicia Gallagher so that he can have custody of her adopted son Jacob when she goes to prison.
However, Wolfenden - who is engaged to Emmerdale co-star Charley Webb (Debbie Dingle) - told TV Times that he would not dream of pulling such a scam in real life.
He explained: "I'm totally different to David and take the marriage vows really seriously. He's so flippant about it and thinks they can get a quickie divorce, but I couldn't do that. It's daft."
The current storyline is leading up to a screen break for Alicia, as Natalie Anderson - who plays her - is expecting her first child with husband James Shepherd.
Wolfenden continued: "I'm really going to miss Natalie. She's great to work with, we have a real ball on set - and I'm looking forward to seeing what happens between David and Alicia."
The actor added that he is still holding out hope for a happy ending for the pair in the long-term. Alicia currently has secret feelings for David, but they are not reciprocated by the shop owner.
He said: "From the build-up, I would love for her to come back and for him to say, 'Let's get divorced' and then, as he's signing the papers, realising that he's in love with her. That would be a great end to this story."
Emmerdale airs David and Alicia's wedding next Thursday (July 5) on ITV1.
