THIS FINAL CONCLUSION NEEDS AN EDIT:
In summary, a California court will likely determine that Alan can inherit from Rebecca as her equitably adopted son because both elements under the doctrine of equitable adoption are satisfied based on clear and convincing evidence. The doctrine of equitable adoption requires an intent to adopt. Rebecca expressed her intent of wanting to adopt Alan, promised to do so, and acted in part performance to carry out the promise to adopt. Rebecca also acted consistent upon that intent by forming a close and enduring familial relationship with Alan throughout the years when she did not deteriorate before her death. Rebecca portrayed to the community at large that Alan was her son, and at all times they both held each other out as mother and son. Thus, a court will likely grant Alan's petition to inherit from Rebecca's estate as her natural son.
THE EDIT WILL CORRECT THE FOLLOWING:
AFTER THE EDIT, THE FINAL CONCLUSION IS NOW ACCOMPLISHED:
Alan can establish by clear and convincing evidence that he was equitably adopted. Alan will likely satisfy the element of intent because on several occasions Rebecca told Alan and others that she wanted to adopt him. Finally, Alan will likely satisfy the parent-child relationship requirement because he and Rebecca held each other out to the community, and cared for and loved each other, as mother and son. Accordingly, as her equitably adopted child, Alan will likely share in Rebecca's estate along with her natural daughter.
THE FINAL CONCLUSION IS ACCOMPLISHED FOR THESE REASONS:
