Help! Waterlogged lawn

[guym]

Hey everyone,
We recently bought and moved into our first home (yay!). Over the last few weeks I have been getting the back garden fixed up which is going well. The issue I have is with the front lawn. It's very boggy and even though we haven't had much rain the mud persists. There are two areas of concern:
1) At the very front of the house the lawn has completely deteriorated and it's pure mud, people park cars there sometimes and it just makes it worse
2) In the middle of the lawn remains wet and waterlogged and the postman rips it up with his motorcycle when he drives by
I was wondering if there is any way to fix this, I was thinking stones and the very front to address the mud but really have no idea. Any help would be appreciated, it's a real eyesore! Added some images to show you what I'm talking about
Thanks

If it hasn't rained much and it stays wet, where is all the water coming from? Until you address this, there is no way to fix the problem. It is possible the water is coming from somewhere uphill from you. Can't you call the city and have them find out where the water is coming from and have them fix it? You can do all sorts of things but as long as water keeps draining in it will remain wet.
