How can i learn project management and law management skills?

It depends from person to person. If you find yourself interested in the field, you might be able to understand the subject without anyone's help. Self-study is the best in this case. If you need someone's assistance take a course. Courses are available ranging from 3 days to MS in the subjects. It's you who has to make a decision. The advice of Mr. Yaqoob is also worthwhile.

thanks for invitation ....

i agree with previous answers

Project management fundamentally is about managing people, not tools. Tools are there to assist. The types of tools/applications used depends on the need of the project. MS project is the easiest one to learn and the one that is most commonly used.

I would say the more important skill for a project manager is soft skills. What do you do when the project is running behind schedule? What would you do when a key team member unexpectedly quit? How do you keep a disgruntled client happy? Etc.

Project Management:

1.  Please read any standard book on project management and discuss the same who is practicing project management chapter by chapter, you will get good start in Project Management

2.  Attend a six week /twelve course on project Management in an institutional setting, you will become a good project Manager

3.  Finally, you may opt for PMP course and get a PMP certification (may take two to three years), you will become Certified Project Management Professional 

When you say law Management, I would assume Business Law rather than “degree in Law”. If this is business law, this will be covered in Project Management course or else, you learn through self-study or attending a short course in Business law.

by take PMP for project

and read in law or go workshop days to learn it very well
