If you have done well in your life in terms of money and success, then you are one of the luckiest people on earth. However, now it’s your responsibility to make sure that your wealth is equally distributed among your children once you are gone without any dispute. What you can do is hire a trust company for this purpose that can take care of all the legal implications.
Make sure you hire the best company for this job as it’s a critical process. Do this and wealth distribution will not seem as difficult as it seems now.
